Linking Environmental Impact Assessment (EIA) with mega infrastructure projects represents a critical research direction within the field of sustainable development. EIA enables the identification, prediction, and evaluation of potential environmental, social, and health impacts of large-scale construction and infrastructure interventions (such as highways, dams, airports, and railway networks). Through systematic analysis at the early planning stage, EIA provides a foundation for informed decision-making and the implementation of mitigation measures to reduce negative impacts.
In a research context, EIA can be utilized as a tool to analyze the effectiveness of existing regulatory frameworks, integrate participatory planning, assess cumulative impacts, and introduce green infrastructure principles. The integration of these domains contributes to the development of models that balance economic development needs with environmental protection, which is essential for responsible land use and resource management in major infrastructure projects.
